The son of influential '80s music label head, Bill Tolson, is now believed to have been murdered after he died in 2015.
As Sunday Herald Sun reports, Connor Tolson's death was considered an accident after his body was found following a fire at his mother's Malvern East home.
However, coronial investigators have discovered Tolson, who was a drummer in local band Riders Of Sin, was dead by the time the bungalow he was found in was set ablaze.
A forensic report released last year revealed Tolson suffered a number of injuries, including a dislocated arm or shoulder and bruises around the neck.
Bill Tolson, who founded Rampant Releases (Not Drowning Waving, These Future Kings, Scrap Museum), believes his son was "strangled" by a man well known to his family and who has a severe mental illness. The man had a number of court orders instructing to keep away from the Malvern East house and was later found asleep in a neighbour's yard following the fire.
"I wanted to believe it was an accident, but once more information came out, it pointed in the one direction towards (name withheld)," Tolson said.
"The police can’t place him there and say he probably can’t even remember being there."
Police confirmed to Tolson that charges would likely not be made against the alleged offender due to his mental state.
Findings from a coroner are expected to be delivered this month.
Tolson currently writes, records and releases music on Rampant.
